In your own words explain what is problem-solving

Jerry purchased a notebook for $350, a pen for $120 and a pencil for $50 with $1,000 and then he received $480 for his change. Using the IPO concept explain what were the inputs, the processing and the output of this problem.

Your mother asked you to go to the shop to purchase 1 (lb) pound of flour and 1 bottle of cooking oil. Create an algorithm listing the sequence of steps you will take to purchase the items.

Create an algorithm for brushing your teeth. Number each step in order so that there is a clear sequence.

You are given the problem of finding the product of two numbers.

1. What input information do you need?

2. What processing needs to take place?

3. What is the goal or output?
